Abstract
The utility model discloses a high-temperature, high-voltage submersible power cable which not only can meet the mechanical properties and electric properties of an earth wire for a power system but also can meet the requirements of work under high temperature and high voltage. The power cable comprises cable conductors and an armour layer, insulating layers, sheath layers, oil-resistant packing layers and armour packing layers are sequentially arranged between the cable conductors and the armour layer as well, and each insulating layer is a combination insulating layer, and consists of an inner insulating layer and an outer insulating layer. The insulating property and temperature class of the cable are greatly increased, the power cable is suitable for supplying electricity to submersible electric pump units with voltage less than 6000v, the long-term operating temperature of the conductors is negative 30 DEG C to positive 232 DEG C, and meanwhile, since the power cable is provided with the lead sheath layers, the armour layer, the oil-resistant packing layers and the like, so the cable has the characteristics of excellent oil resistance, heat resistance, electric insulativity, corrosion resistance, high efficiency, energy saving and the like.
Description
Technical field
The utility model relates to a kind of cable, specifically, relates to the latent oily power cable of a kind of HTHP.
Background technology
The electric cable of submersible pump of prior art belongs to novel product from domestic.Exploitation along with the international market in 2005; The increase of product quantity, product category be variation also, and large-scale electric cable of submersible pump demand increases gradually; Good market prospects is so performance is remarkable, reliable in quality, energy-efficient cable product are the keys that obtains market; But the electric cable of submersible pump that uses in the market is aspect high temperature resistant and high-voltage performance or not fully up to expectations, and this is the existing in prior technology weak point.
The utility model content
The technical problem that the utility model will solve provides a kind of ground wire mechanical performance and electric property that can not only satisfy electric power system, can also satisfy the latent oily power cable of HTHP of the job requirement under the HTHP situation.
The utility model adopts following technical scheme to realize goal of the invention:
The utility model HTHP oily power cable of diving; Comprise cable conductor, armour; It is characterized in that also being provided with successively between said cable conductor and the armour insulating barrier, restrictive coating, oil resistant bed course and armouring bed course; Described insulating barrier is the combined insulation layer, comprises inner insulating layer, external insulation layer.
As the further qualification to the present technique scheme, said cable conductor is many.
As the further qualification to the present technique scheme, described inner insulating layer is processed by polyimides-F46 laminated film sintering, and external insulation layer is made up of the EPDM rubber.
As the further qualification to the present technique scheme, described restrictive coating is the lead sheath layer.
Compared with prior art, advantage of the utility model and good effect are:
Because cable adopts combined insulation layer high temperature resistant and high-voltage performance in this scheme, can increase substantially the insulation property and the temperature resistant grade of cable.This cable is applicable to the supporting power supply of voltage less than 6000v and following Electric Submersible Pump Unit; Conductor long-time running temperature-30 ℃ ~+232 ℃ and following; Simultaneously owing to have a plurality of layers such as lead sheath layer, armour, oil resistant bed course, make cable have excellent oil resistant, heat-resisting, electric insulating quality, characteristics such as corrosion-resistant, energy-efficient; This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1, cable conductor, 2, inner insulating layer, 3, external insulation layer, 4, the lead sheath layer, 5, the oil resistant bed course, 6, the armouring bed course, 7 is armour.
Embodiment
Referring to Fig. 1, the utility model HTHP oily power cable of diving comprises cable conductor 1, armour 7; Said cable conductor 1 outer combined insulation layer, lead sheath layer 4, oil resistant bed course 5 and the armouring bed course 6 of also being provided with successively; Described insulating barrier is the combined insulation layer, comprises inner insulating layer 2, external insulation layer 3, and described inner insulating layer 2 is processed by polyimides-F46 laminated film sintering; External insulation layer 3 is made up of the EPDM rubber; And the thickness of EPDM rubber insulation adopts Unite States Standard, and thickness has improved the high pressure resistant high-temperature behavior of cable greatly greater than national standard.Three cable conductors 1 that the outside respectively is enclosed with combined insulation layer, lead sheath layer 4, oil resistant bed course 5 and armouring bed course 6 are arranged into straight line, become a cable by armour 7 armourings at last.
Certainly; Above-mentioned explanation is not the restriction to the utility model; The utility model also be not limited only to above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also belong to the protection range of the utility model.
